Dunns RIver Falls was excellent. Locals were scary and we felt a little uneasy exiting the park...but all in all it was a good excursion. Kids loved it and we would recommend it as long as you are with a group and travel directly there and dont wander off the highway.
San Gervasio ruins was cool and educational. Great exercise as well for walking off the beers and 9 meals a day on the ship. Chakanaab beach was also cool and the kids loved the dolphin swim there. Snorkeling was excellent and all in all a great time.
